Through the use of a specialized soliton field some ÆtherShips are able to circulate fuligen from their stacks to surround the entire ship. This envelope of fuligen makes the ship undetectable by Æthervox, Eloptic and other hyper- luminary sensors. The drawback is that the ship within is almost blind.

The only way of detecting a ship cloaked in a fuligen envelopement device is to detect the occlusion of background stars or detect the use of their Parascope.
